Abstract: Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for multi-camera video stabilization. In some implementations, a video capture device has a first camera and a second camera. The video capture device provides a digital zoom capability permitting user-specified magnification changes within a digital zoom range during video recording. The video capture device is configured to use video data from different cameras over different portions of the digital zoom range. The video capture device can process image data captured using the second camera by applying a set of transformations including (i) a first transformation to a canonical reference space for the second camera, (ii) a second transformation to a canonical reference space for the first camera, and (iii) a third transformation to apply electronic image stabilization to image data in the canonical reference space for the first camera.

Abstract: Methods, systems, and apparatus, including computer programs stored on a computer-readable storage medium, for video stabilization. In some implementations, a computer system obtains frames of a video captured by a recording device using an optical image stabilization (OIS) system.

Abstract: A method for evaluating brittleness of a deep shale reservoir and a computer readable storage medium. The method includes determining a Rickman brittleness index of the deep shale reservoir and determining an effective pressure of the deep shale reservoir according to a pore pressure and an overlying formation pressure of the deep shale reservoir. The Rickman brittleness index is adjusted to obtain the brittleness index of the deep shale reservoir according to an exponential relationship of the brittleness index with the effective pressure of the deep shale reservoir. Inherent properties, such as rock brittle mineral content and the like, are better indicated by the Rickamn brittleness index, and then the brittleness index of the deep shale reservoir is obtained by utilizing the exponential relationship of the brittleness index with the effective pressure of the deep shale reservoir, to realize reasonable evaluation for the brittleness of the deep shale reservoir.

Abstract: Implementations generally relate to locking a camera onto a sub-region to capture images of the sub-region with a moving camera. In some implementations, a method includes determining a first region in a scene detected by a camera while the camera is in a first physical position. The method further includes receiving user input to target a sub-region within the first capture region of the scene and capturing the first image of the sub-region while the camera is in the first physical position. The first image is displayed in a fixed orientation on a preview portion of a display screen. The camera is moved to a second physical position and a second capture region of the scene is detected. The method further includes capturing a second image is of the sub-region and displaying it in the fixed orientation on the preview portion of the display screen. The second image is effective to inform a user of whether capture of the sub-region is altered by camera movement.

Abstract: A light-field camera may generate four-dimensional light-field data indicative of incoming light. The light-field camera may have an aperture configured to receive the incoming light, an image sensor, and a microlens array configured to redirect the incoming light at the image sensor. The image sensor may receive the incoming light and, based on the incoming light, generate the four-dimensional light-field data, which may have first and second spatial dimensions and first and second angular dimensions. The first angular dimension may have a first resolution higher than a second resolution of the second angular dimension.

Abstract: Methods and apparatus for increasing voltage breakdown levels of an electrostatic chuck in a process chamber. A soft anodization layer with a thickness of greater than zero and less than approximately 10 microns is formed on an aluminum base of the electrostatic chuck. The soft anodization layer remains thermally elastic in a temperature range of approximately ?50 degrees Celsius to approximately 100 degrees Celsius. An alumina spray coating is then applied on the soft anodization layer. The soft anodization layer provides thermal stress relief between the aluminum base and the alumina spray coating to reduce/eliminate cracking caused by the thermal expansion rate differences between the aluminum base and the alumina spray coating.
